it would be helpful to avoid some guesswork if we knew what a few buttons functions were
its Korean.
I figured out how to play games and go to the problems through trail and error;
but i still would like to figure out the translation to some of the other main buttons.

What button Does What?

same question for the 3 bottom buttons and the top left button?

same question for the 4 buttons at the bottom and two buttons at the top?
Thank you in advance
i appreciate your kindness?
